To all whom it may concern I Be it knownthat I, EDWARD W. NnwnLL,

a'citizen of the United States, residing a Pittsburgh, in the county ofAllegheny an Y escapes upon detonation of the projectile.

A 1 front end with a member 3.

' atinfilposition.

In the accompanying drawing; Figure 1 is a central longitudinal sectionof a projectile embodying my invention, showing the primer in itsoperative position; and Fig. .2 a similar view of the nose portion ofthe projectile, with the primer in its non-operile my invention may beemployed in nnection with a time fuse'controlled projectile, the same isillustrated in the drawmg as applied to a projectile adapted to bedetonated by impact.

As ,shown, the projectile may comprise a section of tubing 1 adapted tobe attached by I screw threads to the base portion 2 and having screwthreaded enga ment at the e nose portion 4 of the rojectile is screwedonto the member 3 an a cap member 5 is screwed into said nose portion 4.p

Mounted within the member 3 and adapted for ion "tudinal movement is afiring lunger 6 ving a forwardly extending ammer portion 7 andarearwardly extendcup portion 8 adapted to contain a carti i dge 9formed of amaterial suitable for forming an obnoxious gas when ignited.

Forwardly of and in alinement with the hammer portion 7 ,,a primerholder 10containing a .primer 11 is mounted in the nose portion 4. g

In operation, with the parts positioned as shown in Fig. 1 of thedrawing, when the projectile is firedand strikes an objeet, inertia,causes the continued movement of the firing'plunger 8 relative to theprojectile, causing the spring ring 18 to expand and permit the outwardmovement of the plunger, so that the hammer 7 strikes the primer 11andthe flame from the primer then passes througha central aperture 12 inthe hammer 7 tea central aperture in the cartridge 9, igniting thecartridge to produce gas.

To facilitate the quick combustion of the cartridge, openings 13 mayalso be provided in the member 6,'and the rear end of the primer holderis slotted, so that the flame from the ignited primer 11 can readilypass through the holes 13 to the cartridge.

The flame from the primer also passes through the opening in thecartridge 9 to the usual tube 14.- leadi to the projectile explosivecharge 15 and since the flame must pass the cartridge and ignite samebefore the flame reaches the ex losive charge, it

'will be seen that the gas is sure to be produced before the projectileis detonated.

In order to provide for the prevention of accidental, explosion of theprojectile in. handling, etc., the primer holder 10 may be madereversible, so that when transported, the rimer holder is placed asshown in Fig. 2 o the drawing, with a knob 16' adapted to take the blowof the firing hammer 7 in case of accidental forward movement of same.

In order to indicate that the projectile is in an inoperative position,a projecting washer 17 may be interposed between the cap 5 and the noseportion 4 when the parts are screwed together.

When it is desired to put the projectile in operating condition, the,cap 5'1s unscrewed, the primer holder is turned around, so that theprimer side is presented to the firing plunger as shown in Fig. .1, the.

before detonation, does away with the use of any charging a paratus.

' Havin now escribed my invention, what I c aim as new and desire tosecure by Letters Patent, is I 1. A rojectile comprising a casing, aprimer t erein, and a firing plunger containing a cartridge formed ofasubstance adapted upon ignition to generate an obnoxious gas.

2. A projectile comprising a casing con- 5 taining a primer, ane'xploslve charge,- and a firing plunger located between the primer andthe explosive charge and carrying a substance adapted upon ignition toEDWARD W. NEWELL.
